right i am pretty sure i am thinking right but i hit a speed bump bit faster than i should of done and got a right thump from underneath due to the car being so low. anyway ten mins later when i had turned the car off and restarted the engine light came on. with these codes. p0135 p0131 and p1131 all relating to the front lambda sensor. think thats a good indication the sensor is fooked! Agree??
